Description

Technical Field

[0001] The invention relates to the field of pool cleaning, and in particular to a water intake pump room pool backwashing device and a use method thereof. Background Art

[0002] In water supply and drainage projects, water intake pumphouses typically have inlet and suction tanks for storing water. However, over long periods of operation, silt and impurities easily accumulate at the bottoms of the inlet and suction tanks. If not cleaned promptly, this can lead to a decline in water quality, blockage of the water diversion pipes, and increased wear on the pumps, thus impacting stable water supply. To regularly remove sediment from the bottom of the tanks, manual dredging is currently the most common method. This method is not only labor-intensive and inefficient, but also requires the pumphouse to be shut down, impacting the continuity of water supply. Furthermore, manual dredging cannot reach the water diversion pipes, which, if left uncleaned for extended periods, can become clogged and silted, resulting in poor or even no water inflow. Summary of the Invention

[0003] The purpose of the present invention is to provide a water intake pump room pool backwashing device and its use method, which avoids the traditional manual dredging method, stirs the mud and sand at the bottom of the water inlet pool and the water suction pool, and discharges the mixed mud and water to achieve the effect of dredging the pool bottom, and can also backwash the water diversion pipe at the same time.

[0004] One of the objectives of the present invention is achieved through the following technical solution:

[0005] A water intake pump room water pool backwash device, comprising a plurality of water inlet pools, a plurality of water suction pools and a backwash mechanism; the plurality of water inlet pools are arranged in sequence along the left and right directions, a communication port is provided between two adjacent water inlet pools, and a water stop valve is installed at the communication port;

[0006] The plurality of water suction pools are arranged on the rear side of the water inlet pool in a one-to-one correspondence, and the water suction pools are connected to the corresponding water inlet pools; a water diversion pipe is installed on the front side of each water inlet pool, the front end of the water diversion pipe is connected to the external water source, and the rear end of the water diversion pipe is installed with a quick-opening valve located in the water inlet pool;

[0007] A water pump is installed on the rear side of each water absorption tank, and a water supply network for supplying water to the outside is connected between each water absorption tank, and the water inlet end of the water supply network extends into each water absorption tank;

[0008] The backwash mechanism includes an electric branch valve, an electric main valve, and a flushing main pipe connected to the water supply network through the electric main valve. The flushing main pipe is arranged on the upper side of the water inlet tank and the water suction tank, and a plurality of flushing branches corresponding to each water suction tank and each water inlet tank are extended from the flushing main pipe;

[0009] The flushing branch pipe is connected to a plurality of connecting pipes extending downward, and the electric branch pipe valve is installed between the connecting pipe and the flushing branch pipe. Water flows through the connecting pipe to flush the bottom of the water inlet pool or the water absorption pool, thereby stirring the sediment at the bottom of the water inlet pool or the water absorption pool.

[0010] The second object of the present invention is achieved through the following technical solutions:

[0011] A method for using a water pump room pool backwash device comprises the following steps:

[0012] S1: Open the quick-opening valve and the water stop valve. The external water source flows into the left and right water inlet pools and the corresponding water suction pools through the water diversion pipe. At this time, start the water pump to pump water so that the water in the water inlet pool and the water suction pool is at the normal operating water level, so as to achieve continuous water supply to the outside.

[0013] S2: Close the water stop valve, and then arbitrarily select the water inlet tank on one side and its corresponding water suction tank to form the water pool to be desilted, and the water inlet tank on the other side and its corresponding water suction tank to form the water storage tank for the water pool to be desilted;

[0014] S3: Close the quick-opening valve in the pool to be desilted and the water pump behind it, so that water does not flow in or out of the pool to be desilted; at the same time, open the electric main valve on the flushing main pipe and the electric branch valve corresponding to the pool to be desilted, and then start the water pump behind the water storage tank to extract the water in the water storage tank. The water flows in sequence through the flushing main pipe, flushing branch pipe, connecting pipe and bent pipe into the pool to be desilted;

[0015] S4: Water flows through the bent pipe in the opposite direction of the outflow direction and is injected into the bottom of the pool to be desilted. Vortexes are formed in the inlet pool and the suction pool respectively to stir the sediment at the bottom of the pool. When the water level in the inlet pool rises to the preset backwash level, the level meter sends a signal to control the closing of the corresponding electric branch valve and the electric main valve.

[0016] S5: Open the quick-opening valve corresponding to the pool to be desilted, and use the height difference between the water level in the pool and the normal water level of the external natural water area to discharge the muddy water in the pool into the river through the water diversion pipe, and at the same time backwash the water diversion pipe;

[0017] S6: After the water level in the dredging pool drops to the same level as the normal water level in the natural water area, the backwashing and dredging operation of the pool to be dredged is completed, and then the water inlet pool and the water absorption pool on the other side are backwashed and dredged according to the above steps S1 to S5.

[0018] Compared with the prior art, the advantages of the present invention are:

[0019] 1. By setting up flushing main pipes, flushing branches, connecting pipes and bend pipes, water flows through the bend pipes with the opposite water outflow direction and is injected into the bottom of the water inlet pool and the water absorption pool to be desilted. The water flow forms a vortex at the bottom of the pool to stir up the sediment deposited at the bottom of the pool. The height difference between the water level in the pool and the external water source causes the sewage in the pool to be discharged in the opposite direction to the external water source through the water diversion pipe, thereby achieving pool bottom desilting and backwashing of the water diversion pipe;

[0020] 2. By setting up a liquid level gauge, quick-opening valve, electric branch valve and electric main valve, when the water in the water inlet pool reaches the preset backwash water level, the liquid level gauge is triggered and cooperates with the quick-opening valve to discharge the water from the water diversion pipe, thereby realizing automatic silt removal without human intervention.

DETAILED DESCRIPTION

[0026] The present invention is described in detail below with reference to the accompanying drawings and embodiments:

[0027] like Figure 1-4 FIG. 1 is a schematic diagram of an embodiment of a backwash device for a water pump room provided by the present invention:

[0028] A water intake pump room water pool backwash device, comprising a plurality of water inlet pools 1, a plurality of water suction pools 2 and a backwash mechanism; the plurality of water inlet pools 1 are arranged in sequence along the left and right directions, a communication port is provided between two adjacent water inlet pools 1, and a water stop valve 4 is installed at the communication port;

[0029] Several of the water absorption pools 2 are arranged in a one-to-one correspondence at the rear side of the water inlet pool 1, and the water absorption pools 2 are connected to the corresponding water inlet pools 1; a water diversion pipe 5 is installed on the front side of each water inlet pool 1, the front end of the water diversion pipe 5 is connected to the external water source, and the rear end of the water diversion pipe 5 is installed with a quick-opening valve 6 located in the water inlet pool 1;

[0030] Specifically, a water hole is provided between the water absorption pool 2 and the corresponding water inlet pool 1 , and the water absorption pool 2 and the corresponding water inlet pool 1 are connected through the water hole.

[0031] A water pump 7 is installed on the rear side of each water absorption tank 2. A water supply network 8 for supplying water to the outside is connected between each water absorption tank 2, and the water inlet end of the water supply network 8 extends into each water absorption tank 2;

[0032] The backwash mechanism includes an electric branch valve 31, an electric main valve 32, and a flushing main pipe 33 connected to the water supply network 8 through the electric main valve 32. The flushing main pipe 33 is arranged on the upper side of the water inlet tank 1 and the water suction tank 2, and a plurality of flushing branches 34 corresponding to each water suction tank 2 and each water inlet tank 1 are extended from the flushing main pipe 33;

[0033] The flushing branch pipe 34 is connected to a plurality of connecting pipes 35 extending downward, and the electric branch pipe valve 31 is installed between the connecting pipe 35 and the flushing branch pipe 34. Water flows through the connecting pipe 35 to flush the bottom of the water inlet pool 1 or the water absorption pool 2, thereby stirring the sediment at the bottom of the water inlet pool 1 or the water absorption pool 2.

[0034] Specifically, in some embodiments, the water is directly discharged through the connecting pipe 35, and the discharged water impacts the sediment at the bottom of the water inlet pool 1 or the water absorption pool 2, thereby mixing the sediment with the water.

[0035] The quick-opening valve 6 includes a valve body 61, a screw 62, and a hand-operated and electric-operated opening and closing device 63 for driving the screw 62 to move longitudinally. The side wall of the valve body 61 has a side valve port, and the bottom of the valve body 61 has a bottom valve port. The side valve port is connected to the water diversion pipe 5.

[0036] The hand-operated and electric-powered opening and closing machine 63 is installed on the top side of the water inlet pool 1, and the screw 62 is arranged in the vertical direction. The upper end of the screw 62 is connected to the hand-operated and electric-powered opening and closing machine 63, and the lower end of the screw 62 passes through the top of the valve body 61 and is fixed with a piston plate 65. The outer peripheral wall of the piston plate 65 is sealed with the inner wall of the valve body 61 to block or open the bottom valve port.

[0038] The bottom valve opening is also connected to a downwardly extending lower connecting pipe 66. Specifically, the lower connecting pipe 66 is used to generate a siphon effect during the backwashing and desilting process. This helps drain muddy water from the bottom of the inlet tank 1 and enhances the flushing force of the backwash water flow within the water diversion pipe 5, thereby improving the desilting effect.

[0039] The external water source is a natural water area 100, the water diversion pipe 5 is arranged in a horizontal direction, and the water diversion pipe 5 is located below the normal water level of the natural water area 100; a liquid level gauge 9 for measuring the water level inside the water inlet pool 1 is installed on the top of the water inlet pool 1, the measuring point of the liquid level gauge 9 is located above the normal water level of the natural water area 100, and the liquid level gauge 9 is electrically connected to the electric branch valve 31, the electric main valve 32 and the quick-opening valve 6.

[0040] A plurality of backup pumps 10 are also installed on the rear side of the water absorption tank 2 , and the backup pumps 10 are connected to the water supply network 8 .

[0041] Each flushing branch pipe 34 is connected to two connecting pipes 35, and the two connecting pipes 35 are respectively located on opposite sides of the corresponding water pool; the bottom of the two connecting pipes 35 is connected to a bent pipe 36, and the bent pipe 36 is parallel to the bottom side of the corresponding water pool, and the water outlet directions of the two bent pipes 36 are opposite. The flushing water flows through the two bent pipes 36 and is discharged to form a vortex at the bottom of the corresponding water pool.

[0042] There are two water inlet pools 1 and two water absorption pools 2.

[0043] Preferably, the four corners of the water inlet pool 1 and the water absorption pool 2 are all rounded with concrete to reduce water flow resistance and facilitate the formation of vortexes during backwashing and water injection.

[0044] A method for using a water pump room pool backwash device comprises the following steps:

[0045] S1: Open the quick-opening valve 6 and the water stop valve 4. The external water source flows into the left and right water inlet tanks 1 and the corresponding water suction tank 2 through the water diversion pipe 5. At this time, the water pump 7 is turned on to pump water so that the water in the water inlet tank 1 and the water suction tank 2 is at the normal operating water level 102, so as to achieve continuous water supply to the outside.

[0046] S2: Close the water stop valve 4, and then arbitrarily select the water inlet pool 1 on one side and its corresponding water suction pool 2 to form the water pool to be desilted, and the water inlet pool 1 on the other side and its corresponding water suction pool 2 to form the water storage tank for the water pool to be desilted;

[0047] S3: Close the quick-opening valve 6 in the pool to be desilted and the water pump 7 behind it, so that water does not flow in or out of the pool to be desilted. At the same time, open the electric main valve 32 on the flushing main pipe 33 and the electric branch pipe valve 31 corresponding to the pool to be desilted. Then start the water pump 7 at the rear of the water storage tank to extract the water from the water storage tank. The water flows in sequence through the flushing main pipe 33, the flushing branch pipe 34, the connecting pipe 35 and the bent pipe 36 into the pool to be desilted.

[0048] S4: Water flows through the bent pipe 36 in the opposite direction of the water outflow and is injected into the bottom of the pool to be desilted. Vortexes are formed in the inlet pool 1 and the suction pool 2, respectively, to stir the sediment at the bottom of the pool. When the water level in the inlet pool 1 rises to the preset backwash water level 101, the level meter 9 sends a signal to control the closing of the corresponding electric branch valve 31 and the electric main valve 32.

[0049] S5: Open the quick-opening valve 6 corresponding to the pool to be desilted, and use the height difference between the water level in the pool and the normal water level of the external natural water area to discharge the muddy water in the pool into the river through the water diversion pipe 5, and at the same time backwash the water diversion pipe 5;

[0050] S6: After the water level in the dredging pool drops to the same level as the normal water level of the natural water area, the backwashing and dredging operation of the pool to be dredged is completed, and then the backwashing and dredging of the water inlet pool 1 and the water absorption pool 2 on the other side are performed according to the above steps S1 to S5.
